<div>Wayne喜欢网格，所以他把一些网站排成了N_ M的网格，每个格子代表一个网站。每个网</div>
<div>站有一个评分，当然评分可正可负。现在Wayne想用一堵&ldquo;墙&rdquo;围住一些网站，使得评分和最大。</div>
<div>所谓&ldquo;墙&rdquo;，就是一个由网格的边组成的简单多边形，不能自交，也不能有空洞。</div>
<div>过了一会儿Wayne发现这个模型太一般了。出于一些原因，有些网站必须在&ldquo;墙&rdquo;外，我们称之</div>
<div>为&ldquo;坏网站&rdquo;；而有些网站必须在&ldquo;墙&rdquo;内，我们称之为&ldquo;好网站&rdquo;。当然了，&ldquo;坏网站&rdquo;的评分不一定</div>
<div>低，&ldquo;好网站&rdquo;的评分不一定高。Wayne又想知道，这种情况下，能够得到的最大评分和。注意，并</div>
<div>不总是存在合法的方案，所以当无法实现时，输出&ldquo;Can not establish GFW.&rdquo;。</div>
<div></div>
<p></p></p><hr/><h3>输入格式</h3><p><div></div>
<div>第一行两个正整数N和M。</div>
<div>接下来N行，每行M个用空格隔开的整数，表示网站的权值。</div>
<div>最后N行，每行M个用空格隔开的整数，1 表示坏网站，2 表示好网站，0 表示其他网站。</div>
<div>
<p></p>
</div></p><hr/><h3>输出格式</h3><p><div>输出两行，第一行一个整数表示一堵&ldquo;墙&rdquo;能围住的最大评分和，第二行表示有限制时的答案。</div>
<div></div>
<p></p></p><hr/><h3>样例输入</h3><pre>3 3
2 -1 2
-3 100 -3
-3 20 -3
2 0 2
0 1 0
0 0 0</pre><hr/><h3>样例输出</h3><pre>123
